Please select the correct version to match your printer. Look at the rear of your extruder and see if it has the latching pins or if the ribbon cable plugs in directly.
The PCB's are not interchangeable and you must select the correct version. Selecting the incorrect board will lead to damage to your gMax printer. If you have any questions on which board to select, please email us prior to purchasing.
v.1 Does not have latching pins. Ribbon cable plugs in directly.
v.2 & v.3 (Note v.3 has replaced v.2) Have latching pins.
